If you have come across a daunting problem in MS word where a new blank page appears without your volition and you lose your mind cos you just can’t delete it, relax, the following will restore your peace if it already was available to you before MS misbehaved. We have covered your back. Sorry I copied the following magical solution from a comment section from the web after suffering silently the fool that “software helplessness” is. Yes, the following works like a charming mother in law. Thanks MILs. More…

Finally I am successful in calculating pi value — less than 0.3% error, by using random number generation. Although my computer needs some fixation on its compiler or path definition etc, there are very good online compilers which helps in testing and running c++ codes: try the given link.

Here is the code I found by searching a good deal on the web. Yes I did tinker around but only because my own compiler (Turbo C++ on windows 10, 64 bits) was throwing some exceptions on the included headers.

Why information is more and more viral, if its got more statistics? Because it sits on more and more number of servers which are being accessed in a randomized fashion there is increase in the statistics and thus possible viral tendencies.

When you are reading an article on a large computer system, lets say a NY times article another person isn’t accessing the same servers, given a particular server can be accessed lest say by only 100 people. Thus NY times has to buy more number of computer servers and more bandwidth etc. More…

It reflects the quality scope of the citations. Its the total percentage of a citation that goes into defining a particular citation index. Let me call it q-index therefore (q for quality)

See this example.

My h-ind is 60. So total (minimum) citation it accounts for is 60*60 = 3600. My total citation is 12215. So my q-ind is 3600/12215 = 29.47% Or 29.47% of my total citation were important for this parameter. Hence my q-index is 29.47. In this way if someone has 500 total citation with h-index 60, he has a much better q-index than mine, because more of his paper are highly cited More…

2. The object can be a large object, eg say something whose picture you are taking. But as explained above its not the energy of the object (or momentum) which is directly coming into the problem. That would be an added degree of concern if the object is moving with certain velocity, a reason why pictures are blurred. Because motion of objects introduces additional energy-time-momentum-position variables and their corresponding uncertainties. For the argument of the above problem one can imagine the large sized object, lets say a bird, is standing still on a tree while its picture is being taken. In that case if the wavelength of the light [few 100 nano meters = 1/10th of a micrometer] is used (eg in a digital-camera) the corresponding accuracy of the light will be less than micrometers. You can take a very sharp picture of the bird, which is lets say 6 inch long. But when you zoom in to a large degree, the inaccuracies will show up. [in this case how to see a micrometer level image? Is a computer sufficient to show us the uncertain edges of the pixels?] If the wavelength (here visible light) is so small, evidently by de-Broglie relationship, momentum or energy of such light is very large. But its not as large to disturb the feelings of the bird. The bird doesn’t have a problem with visible light, and such energy does not disturb its position or energy or any thing so to say. So while Quantum Mechanics is valid, we are accustomed to say this is a classical mechanics situation. To say QM is invalid is incorrect. To say QM is understood to be valid is a knowledgeable position. More…

Couple years ago, for this reason, not the kai reason, but any phonetic-word-attempt which gave me tons of kanjis, for same phonetics, I said, Japanese Language has so many synonyms, (perhaps this is anti-synonym, but in my defense, I don’t remember exact word I used, its a memory retrieval, you see) and still Japanese Language unites them all and makes into one language; we can also do this for Indian language.
Indian (Language) would be far easier (than the complexity of Japanese) in that, given, lets say, jack-fruit will have 8 different words only, across India, then, we have to put them all into one syllable-alphabet unit (that can be newly defined, because now we have at-least 20 ways to define) eg Hindi: kathar/kathal, Odi: panas (Telugu also Panas, I know, I asked this to my friend 15 years ago, he was from AP, his name Venkateswaralu Goruganthi, funny fella with thilak on his head, see since when I am doing my language research?) I don’t know more language, lets say: Gujurati: xyz.

Then take all Indian Language and list these into one unit. That unit would be given a special phonetic tag. (Because we don’t have any) The reverse of this has been accomplished by Japanese. By having each meaning for a single phonetic or syllable unit as a kanji (or pictorial unit) they have unified language. Back then I said, 20 some synonyms, (so many = 20) Lets count today.
As if a coincidence I found 20. Although, there would be, some redundant issues here (eg 買い and 買 ) and a few more may be left. (eg I remember, now I know some Japanese Language by memory: kai = write, kai in kaishi = begin). Lets see what we found in Japanese for kai; each of the following is kai, with different meaning. Only one is (sa)kai and couple are not known (just kai, in 2nd line), from where I am searching. Lets then, give their meaning.
